Washing Machines
Leveraging the full-chain synergy of its IDM model, crmicro provides customers with complete solutions for high-reliability brushless motor control, compressors, PFC and main controllers, as well as semiconductor devices，which helps customers achieve efficient, energy-saving, stable and reliable home appliances.
Solution Overview
Targeting the electronic control system of variable-frequency washing machines, the solution integrates a complete set of chips including a wide-input power supply, advanced FOC algorithm for permanent magnet motors, signal isolation, and panel display. Using power devices (IPM/IGBT/SiC MOSFET/SiC diode), PMICs, dedicated high-performance MCUs, gate drivers and optocouplers, it delivers smooth high-torque output and dynamic load adaptation, optimizing overall energy efficiency and shock resistance under frequent start-stop conditions.
Solution Advantages
-
High-integration IPM module drive delivers a quiet, smooth, and powerful variable-frequency motor
-
Optimized power devices reduce energy consumption, and improve appliance energy efficiency class
-
Multiple safety protections, strong anti-interference, more reliable operation
-
MCU FOC algorithm supports multi-mode washing with precise speed regulation, combining fabric care with cleaning performance
